  • Amélioration de la version de base

    13 septembre 2013

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Menus personnalisés

    14 novembre 2010, par

    MediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
    Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
    Menus créés à l’initialisation du site
    Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...)

  • MediaSPIP Core : La Configuration

    9 novembre 2010, par

    MediaSPIP Core fournit par défaut trois pages différentes de configuration (ces pages utilisent le plugin de configuration CFG pour fonctionner) : une page spécifique à la configuration générale du squelettes ; une page spécifique à la configuration de la page d’accueil du site ; une page spécifique à la configuration des secteurs ;
    Il fournit également une page supplémentaire qui n’apparait que lorsque certains plugins sont activés permettant de contrôler l’affichage et les fonctionnalités spécifiques (...)

  • Java.lang.NoClassDefFoundError caused by FFmpeg when deployed on Linux as a packaged .war (Works on development machine)

    27 décembre 2016, par Jake Miller

    I use an FFmpeg wrapper to create thumbnails for videos uploaded by users. This works perfectly fine when testing on my development machine. However, whenever I package my project as a .war and deploy to Amazon Web Services, I get the following stack trace :

    Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.bytedeco.javacpp.avutil

    Here’s my maven dependencies for the FFmpeg wrapper :

    <dependency>
    
    <groupid>org.bytedeco</groupid>
    
    <artifactid>javacv</artifactid>
    
    <version>1.3</version>
    
</dependency>

    <artifactid>opencv-platform</artifactid>
    
    <version>3.1.0-1.3</version>
    
</dependency>

    Again, this library works perfectly fine on my development machine.

    • Development machine : Windows 10, 64-bit (Works)

    • AWS instance:64bit Amazon Linux 2016.09 v2.2.0 running Java 8 (Causes the issue above)

    I’ve spent around 7 hours trying to fix the issue by messing around with versions. Any idea how to solve this issue ?

    WHAT I’VE TRIED SO FAR

    • upgrade to Linux to 2.4
    • downgrading javacpp to 1.2.1
    • running mvn clean
    • running mvn -U
    • deleting contents of /.m2/ and redownloading dependencies
    • various combinations of dependency versions
    • git clone on a Linux VM & running mvn install there

  • MP4Box / FFMPEG concat loses audio after first clip

    17 novembre 2017, par user1615343

    So I am certainly no expert when it comes to either of these tools, but I have a web-based project that’s executing commands on an Amazon Linux server to concatenate two video files that are uploaded.

    Both files are converted to mp4s first using FFMPEG, and those play perfectly in a browser after conversion :

    ffmpeg -i file1.mpg -c:v libx264 -crf 22 -c:a aac -strict -2 -movflags faststart file2.mp4

    Then, I attempt to combine these two resulting mp4s into a single mp4. I tried using FFMPEG to do this but to no avail. Switching to try MP4Box got me much closer : the videos are concatenated together, but the audio stops playing at the end of the first clip, and the second clip is silent.

    MP4Box -force-cat -keepsys -add file.mp4 -cat file2.mp4 out.mp4

    I’ve tried varying versions of the above command with no better results. Any input is greatly appreciated.

    EDIT : info on .mp4 files using

    ffmpeg -i file1.mp4 -i file2.mp4

    ffmpeg -i 1510189259715DogRunsintoGlassDoor_315a03a8e20acfc.mp4 -i

  • Reduce latency in ffmpeg snapshot

    3 décembre 2015, par Acorian0

    I have a latency problem with FFMPEG.

    I have a streaming server running and I occasionally need to take multiple snapshots over a period of time (in the example below, 5s), and then examine the snapshots taken. Time is critical.

    With this command I take 25 frames per second over 5 seconds, meaning I will have 125 snapshots in my folder.

    ffmpeg.exe -ss 0.05 -re -i udp://239.255.0.xx:xxxx -ss 0 -vf fps=25 -to 5 -y \Test\%5d.jpg

    The -vf fps is forcing the 25 frames per second even if the server can’t provide them.

    The problem is that -ss 0.05 is not doing its job. It is supposed to delay the initial snapshot for 50 milliseconds but FFMPEG takes around 200ms to "start" the service on itself :/. This means the first snapshot is taken after around 200ms after I called the service. (200ms is way too big of a latency for my purpose... I can survive with 100ms)

    How can I force FFMPEG to start taking snapshots earlier ? Or is there a way to get snapshots, let’s say, from the buffer (e.g. start taking snapshots 150ms in the past) ?

    PS : Changing the -ss from 0.05 to 0.00 is not doing anything, I can only see the -ss doing something if the value is bigger than 0.2/0.25. Another thing, using a newer version of FFMPEG is by now impossible
